Neutron diffraction intensity at a position (h, h, 0.5) as a function of h for CeCoIn₅ measured in various high fields close to H_c2. The black circles display the data in the superconducting state, while the grey circles are in the normal state. It can be seen that in the superconducting state the magnetic Bragg peak appears corresponding to the Q-phase, which is absent when the system becomes normal.
